Common Name: Iron Cross Plant

General Information

Oxalis deppei is a perennial herb producing a rosette of leaves about 30cm tall from an underground bulb and taproot.
The leaves and flowers are gathered from the wild and eaten locally. A very ornamental plant, valued for its free flowering habit, it is often grown as an ornamental in gardens[, ].

Known Hazards

The leaves contain oxalic acid, which gives them their sharp flavour. Perfectly all right in small quantities, the leaves should not be eaten in large amounts since oxalic acid can bind up the body's supply of calcium leading to nutritional deficiency. The quantity of oxalic acid will be reduced if the leaves are cooked. People with a tendency to rheumatism, arthritis, gout, kidney stones or hyperacidity should take especial caution if including this plant in their diet since it can aggravate their condition[].
